zig libc: modify errno helper to eliminate @intCast #30918

Merged
andrewrk merged 1 commit from zig-libc-errno-wrapper into master 2026年01月24日 20:18:20 +01:00

The vast majority of libc functions return c_int for the return value, when setting errno. This utility function is for those cases.

Other cases can hand-roll the logic, or additional helpers can be added.
